Magnetic recording and reproducing apparatus |
摘要 |
A magnetic recording/reproducing apparatus has a rotor drum with a group of rotary magnetic heads mounted thereon, a reproducing amplifier, a recording/reproducing mode switching circuit, a head selection circuit, a control circuit and a DC voltage source. The control signal circuit and the DC voltage source receive a control signal transmitted from a stator drum through a rotary transformer and produce signals for controlling the mode switching circuit and the head selecting circuit and a DC voltage for energizing all the circuits on the rotor drum, respectively.
